MACHINE AND APPARATUS FOR MILKING.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filoil February 23,1907. Harial No. 359,026

To all whom it may concern:

Bo it known that l, STEFAN Bnsrrn, a. subject of the temporarily residing at No. l riodricl'istrzisso. Dresden, in the Kingdom of Saxony, Gui-many, have invented certain new and north] lmprovcnionts in Machincso Appamtns for lllilkinggiiwhich the following is a specification.

The present invention has reference to improve? moms in nmchanical applianccs for milking and its special loatnro consists in the regulatiori ol the suction l which the machine exerts on the dogs or tcats oi the animal lacing in complete accordance with the natural conditions which prevaiLat the initial, culminating andfinishinghtages of the procss of milking.

By the use of many of th machines and appliances for milking hitherto known, thcie is a liahilit'y to injure tho udder of thdaniinal by irregular and unnatuml exortion, in consequence of which inflammation and other undesirable effects may bc prodncd. By the use of this invention the before mentioned and other similar drawbacks oi milking with machines are removed. l

The contrivance I employ isgdistingitished by its simplicity'snd conformity to nfitmo At the some time it is quite oiioctive, dopendshlia and does. not maku the machine a complicated 0119.. It now of the introduction of an air inlet in the suction diicts, the quantity of air allowod to enter being regulated in strict accordance with the 'flow of milk. .7 V. r

lgiligflaccompanying drawing; Figure I is a vertical of the machine as seen from above and Fig. 3. is a detail lobe hereinafter referred to. V

Tho wholo apparatus is mounted on a form a'. The ducts b, one each of w attaclwd to a dog or test, meet in th tubs b which leads to the common raising tube 0 tho'saidtupe c discharging intovtho incloscd space dthrough thpji'eliefvalve o in the said space d there is a suction sod forcwpump e, which may be worked by any cont nuient and suitable power. Sidewise a duct f provided with a relief valvcf, loads out of the pump space if to the collecting vessel g which the partition I: divides into two compartmonts,' the upper comyortmont 9" and tho lower one the said compartments being conncctod by moans of a suitable opening in the said-pan V Tho lower compartment 9 has an outlet pipe 2' and an overflow pipe 1" both of which conduct to the can k. In the said compartment g there is a, float I, which is connected by means of the rod 1;: and low? in" to the axle n, which projects through the wall of tho compurtmont. Outside, on the projot'ting partoi tliv uxlo 'n, n nmvable'lever o is mounted and connected with tho connecting rod 0' which is jointod on to one vnd oi the scale-beam hung on a support p suitably attached to the frame of the machine.

portable plat ich is suitably 9 being attached to and actuating the sliding valve r of tho pi po 1', Attached to tho hoforc-mcntionod scale-beam p is the slidc 'alvv .s which controls tho opening 8' leading to tho raising who rv To tho scalebcani p a number of hooks l are iiXcd at measured dis tanccs, the said hooks hcing intcnded to hang tho wcigln n on.

Fig: bring only a view of the apparatus as soon from above, and as it docs not show any ii-arts not described in connection with Figs 1 and 3, no further reference is necessary.

3 represents a contrivsnco to he oinployed in conncction with the apparatus when milking animals which by mason of ago or from othoi" causes, require spacial can: in rogulating the snctios: action of tho pump. To eachilnctbasgringringoisattachud The said rings 11 can no distended by handles "a l A short distance below the said ring 'a a case with a hag shapod insets: is inserted in thsduct b. The said inset x isprovided with a sieve x at the bottom, and also has opcnin'gsix at the sides to admit air and provide an outletior the overflowing milk. The hag-shaped inset contains a. float y which is conne ctedlhy means of the lever y with the slidingwaive s which controls ilkair inlet z; I

The machine Works as follows: The piston of 111- pump 9 being-raised, it draws the milk from the tests through the pipe c to t hqspaco d. Whn depressed it. closes the valyo c and forces the milk through the duct 1' to the float conipartment 'sr container 9 from which it runs into 9 automatically. The sebration is provided, in the first place, in order that the pressure wave may be broken on the partition in, and, in the scconii place, to avoid as much as possiljle tho contents of compartmsnt '1 being agitated. When the float 1 tests on the bottom of g, the upper and perforated part of the sliding-valve s is before the opvning s. and, in

consequence of suction, a quantity of air enters c and roducesthe sucking action on the tests 0: dogs to the extent which is necessary at the initial stage of milking. As the milk oollcts the float risos; at the same time the full flow of milk sets in and the action of the pump can be concentrated on the tests. This is caused by the lost rising with the milk and gradually shutting off the inlet of air at 0. While the milk is rising, the arm 1 remains stationary until the float rises high 'cnnugh to press it upward and il'kfi'ieiiflfiififl the slide valve Tl The result of this is, a perforated part of-tho slide moves in front of tho outlvi. i and allows the milk to run into the rctleptaclc k. in this manner the initial stage of the milking prom-ss is performed and tho culminating sings reached. Tho lloat rises as far as it (an and remains in that position untilthe mucosa approachs its and.

The lllilt-lllillg stage is curricll out as [OllOWSI The flow nl' lllilk from the tents (llllilfliHllL'S and gradually clrzwcs.
